I have a compatible amplifier connected to the NAS via USB. I can see that the NAS recognizes the amplifier.

I literally cannot follow the instructions. When I play an audio file, it plays through my computer's speakers. How do I get the audio to play through the USB port?

This is what the documentation says:

"To play music via different devices, you can select your desired output device from the My computer/USB speakers/[Media renderer name] (indicating the device you have been streaming music to) drop-down menu on the control bar, and add songs to individual devices."
